Tax Extension Deadlines

If you need more time to prepare your tax return, you can request an extension. However, keep in mind that an extension does not grant an extension to pay any taxes owed. You must estimate and pay any taxes owed by the original deadline to avoid penalties and interest. 

Key Takeaways

  • Pay what you owe. Try to pay at least 90% of what you owe to avoid penalties. 
  • Extension does not delay payment. You must still pay by April 15, 2025, to avoid penalties on what you owe. 
  • Deadline to file for an extension. You must file an extension by April 15, 2025. 
  • Taxes due if extension requested. Your new deadline for Oct. 15, 2025, if you request an extension to pay your 2024 tax return.

Penalty Breakdown

What is the penalty if you file late? What is the penalty if you fail to pay on time? Here are the penalties you need to keep in mind: 

  • Late filing. If you file your tax return late, you are charged 5% of the unpaid taxes for each month or part of a month that the return is late, up to a maximum of 25% of the unpaid taxes.
  • Late payment. You will pay 0.5% of the unpaid taxes for each month or part of a month after the due date, up to a maximum of 25% of the unpaid taxes.
  • File on time. Filing on time avoids additional fees even if you can’t pay in full. 

State Tax Deadlines 

State tax return deadlines can vary. Many states require you to submit your state tax return on April 15, 2025. However, the following states have different dates for their tax returns: 

  • Delaware: April 30, 2025
  • Hawaii: April 21, 2025
  • Iowa: April 30, 2025
  • Louisiana: May 15, 2025 
  • Virginia: May 1, 2025

Weekend and Holiday Rule

If April 15 falls on a weekend or holiday, the due date for taxes will shift to the next business day.

For instance, if April 15 falls on a Saturday, taxes would be due that following Monday, April 17, to be considered timely. 

Missed Deadline Consequences 

What if you miss your tax deadline? What should you do? 

  • File immediately. Even if you’re unable to pay the full amount that you owe the IRS, file your taxes ASAP. Filing immediately will potentially reduce the penalties you owe. 
  • Consider a payment plan. Contact the IRS and explain your situation. They may work with you to establish a payment plan. 
  • Pay what you can. Paying anything will help reduce your penalties and interest on your tax bill. 
  • Contact a professional. If you need guidance, don’t wait. Contact a tax professional to get some help.

Final Take

If you’re unable to file on time, then request an extension. Even if you file an extension, make sure you pay what you owe. 

FAQ

  • What are my estimated tax payments in 2025?
    • If you have taxable income from being self-employed or you have a business, you will need to make estimated tax payments throughout the year. The IRS requires these payments if you expect to owe at least $1,000 in tax for 2024 after subtracting your withholding and refundable credits. Most W-2 employees meet their tax obligations through regular paycheck withholding.
  • What ways can I file my taxes?
    • There are various ways you can file your taxes:
      • Online or e-filing: Use tax software or online platforms for a convenient and efficient way to file your taxes.
      • Paper filing: If you prefer traditional methods, you can fill out a paper tax return and mail it to the IRS.
      • Professional help or CPAs: Consider hiring a tax professional or accountant to assist you with your tax preparation if you have complex tax situations.
  • What if tax day is on a weekend?
    • If April 15 falls on a weekend or a holiday, the tax deadline usually gets extended to the next business day. So, always double-check the specific deadline each year to avoid any confusion.
  • What is a tax fiscal year?
    • Most individuals file taxes based on the calendar year -- Jan. 1 to Dec. 31. However, some businesses and individuals with specific accounting methods may use a fiscal year -- a 12-month period ending on the last day of any month other than December. You must apply to the IRS to use a fiscal year.
